BACKGROUND

In mathematical terms, a graph is a collection of elements. These elements, which are typically referred to as nodes (or vertices), are joined together by links (or edges). Each node represents an entity to which information can be attached, whereas each link represents a relationship between entities. Information may also be attached to links. Graphs are extremely useful in understanding a wide diversity of datasets.

A database is an organized collection of data. A graph database is a type of database in which one or more graphs are used to model the structural relationships between data objects in a dataset. Graph databases use nodes, links, and properties (or attributes) to represent and store data objects. Generally speaking, the nodes in a given graph represent instances of entities such as people, businesses, accounts, or any other item of interest. The links in the graph represent the connections or relationships that exist between pairs of nodes. Data related to the nodes may be stored as properties of the nodes, whereas data related to the links may be stored as properties of the links.

Graph databases enable users to leverage complex and dynamic relationships in highly connected data (i.e., data whose interpretation and value requires an understanding of the ways in which its constituent elements are related) in order to generate insight and competitive advantage. Graph databases have helped solve important problems in a number of technical areas, including social networking, master data management, fraud detection, recommendation engines, and bioinformatics applications.

SUMMARY

A method for providing a visual representation of a graph is disclosed. In accordance with the method, a current node of interest may be displayed. The current node of interest may include a first plurality of neighbor nodes. A subset of the first plurality of neighbor nodes may be displayed with the current node of interest. Links connecting the subset of the first plurality of neighbor nodes to the current node of interest may also be displayed. The method may also include displaying a user interface element that facilitates navigation to additional neighbor nodes that correspond to the current node of interest but are not currently displayed.

The user interface element may provide information about the subset of the first plurality of neighbor nodes. The user interface element may include a navigation component, and user activation of the navigation component may change the subset of the first plurality of neighbor nodes that are displayed. In some embodiments, a neighbor node indicator may be displayed next to each neighbor node of the current node of interest that includes one or more of its own neighbor nodes.

The current node of interest may be displayed in a central portion of a user interface screen. If user input is received selecting a neighbor node of the current node of interest as a new node of interest, the selected neighbor node may be moved to the central portion of the user interface screen. The new node of interest may include a second plurality of neighbor nodes. The subset of the first plurality of neighbor nodes may be removed from the visual representation, and a subset of the second plurality of neighbor nodes may be displayed with the new node of interest. An animated sequence may be used to remove the subset of the first plurality of neighbor nodes and to display the subset of the second plurality of neighbor nodes. The user interface element may be updated to provide information about the subset of the second plurality of neighbor nodes. In some embodiments, the method may include continuing to display previous nodes of interest when the visual representation is changed to a new node of interest.

A computer system configured to provide a visual representation of a graph is disclosed. The computer system may include one or more processors and memory comprising instructions that are executable by the one or more processors to perform certain operations. The operations may include displaying a current node of interest. The current node of interest may include a first plurality of neighbor nodes. The operations may also include displaying a subset of the first plurality of neighbor nodes with the current node of interest. The operations may also include displaying links connecting the subset of the first plurality of neighbor nodes to the current node of interest. The operations may also include displaying a user interface element that facilitates navigation to additional neighbor nodes that correspond to the current node of interest but are not currently displayed.

A computer-readable medium having computer-executable instructions stored thereon is also disclosed. When executed, the instructions cause one or more processors to perform certain operations. The operations may include displaying a current node of interest. The current node of interest may include a first plurality of neighbor nodes. The operations may also include displaying a subset of the first plurality of neighbor nodes with the current node of interest. The operations may also include displaying links connecting the subset of the first plurality of neighbor nodes to the current node of interest. The operations may also include displaying a user interface element that facilitates navigation to additional neighbor nodes that correspond to the current node of interest but are not currently displayed.

DETAILED DESCRIPTION

As indicated above, graph databases use nodes, links, and properties. Nodes represent entities such as people, businesses, accounts, or any other item of interest. Links connect nodes to other nodes, and they represent some relationship between them. Properties represent particular information about nodes or links. Meaningful patterns may emerge when examining the connections and interconnections of nodes, links, and properties.

Graph databases allow simple and fast retrieval of complex hierarchical structures that may be difficult to model in relational systems. With relational databases, join-intensive query performance tends to deteriorate as the dataset gets larger. In contrast, with a graph database performance tends to remain relatively constant, even as the dataset grows. This is because queries of graph databases are typically localized to a portion of the graph, so that the execution time for each query is proportional only to the size of the part of the graph that was traversed to satisfy the query, rather than the size of the overall graph. As a result, graph databases are increasingly being used to model large, complicated datasets.

As the data being represented in graph databases increases in size and complexity, queries to graph databases may return an extremely large number of nodes (e.g., tens of thousands of nodes or even more). Consequently, it may be difficult to identify any meaningful information from a visual representation of the query results.

The present disclosure is generally related to improved techniques for providing visual representations of a graph. FIG. 1 is a block diagram that illustrates an example of a system 100 in which aspects of the present disclosure may be utilized. The system 100 includes a query-generating entity 102, which may include a device, a computer program, or some other hardware-based or software-based entity that is capable of generating a query 104 to be applied to a graph database 106. The graph database 106 may define a plurality of nodes 108 and links 110 that connect nodes 108 to one another. The nodes 108 may include properties 112 a, and the links 110 may include properties 112 b.

The query-generating entity 102 may be in electronic communication with a query processing system 114 and may be operable to submit the query thereto. The query processing system 114 may be configured to receive the query 104 from the query-generating entity 102 and execute the query 104 against a graph database 106 to obtain query results 116. The query results 116 may include data responsive to the query 104. In particular, the query results 116 may include nodes 108, links 110, and properties 112 a-b that satisfy the query 104.

A visual representation 118 of the query results 116 may be generated and displayed via a user interface 120. The visual representation 118 may be dynamic. For example, the visual representation 118 may include one or more user interface elements 122 that enable a user to interact with the visual representation 118. Consequently, the visual representation 118 of the query results 116 may change in response to user input.

For purposes of example, FIG. 1 shows the visual representation 118 in the context of query results 116 from a graph database 106. However, the scope of the present disclosure should not be limited to this specific context. The visualization techniques disclosed herein may be applied in a variety of other contexts. For example, the techniques disclosed herein may be applied to visually represent a graph that is loaded from a file.

FIG. 1A illustrates different elements of a graph. As indicated above, a graph may include nodes (or vertices) and links (or edges). Nodes may represent objects, and links may represent relationships between objects.

As indicated above, the nodes 108 may include properties 112 a, and the links 110 may include properties 112 b. The properties 112 a-b may take the form of key-value pairs that may include different types of values (e.g., string, Boolean, number). In addition, in some embodiments, the nodes 108 and the links 110 may also include other types of attributes, such as identifiers and labels. Identifiers may uniquely identify each element (node or link) of a graph. Labels may include unique string elements that may be used to identify types of objects (nodes or links).

FIGS. 2A-F illustrate examples of user interface screens 224 a-g that may be displayed in connection with presenting the visual representation 118 of the query results 116. Reference is initially made to the user interface screen 224 a shown in FIG. 2A. A plurality of nodes 208 are displayed. These nodes 208 (and other nodes as well) are included among the query results 116 that have been returned. A node 208 a has been selected (e.g., via user input) to be the node of interest 208 a. The node of interest 208 a is shown in a central portion of the user interface screen 224 a.

Generally speaking, in a graph database 106, two nodes 208 are considered to be neighbors if they are connected to one another via a link 210. The user interface screen 224 a shown in FIG. 2A shows a plurality of neighbor nodes 208 that are connected to the node of interest 208 a via links 210.

The neighbor nodes 208 that are shown in FIG. 2A are only a subset of the total number of neighbor nodes 208 corresponding to the node of interest 208 a. For the sake of simplicity, in the depicted example it will be assumed that the node of interest 208 a includes a total of 22 neighbor nodes 208. However, in a graph database 106 that models large, complicated datasets, a node of interest 208 a may include an extremely large number of neighbor nodes 208 (e.g., tens of thousands or more). If all of the neighbor nodes 208 corresponding to a particular node of interest 208 a were displayed at the same time, it would be very difficult for the user to identify meaningful information from the visual representation 118 of the query results 116.

To address this problem, a visual representation 118 in accordance with the present disclosure may display only a subset of the neighbor nodes 208 that correspond to the node of interest 208 a at any given time. In other words, a maximum number of neighbor nodes 208 (N_(max)) may be defined, and the visual representation 118 may only display N_(max) neighbor nodes 208 at any given time. If the number of neighbor nodes 208 corresponding to the node of interest 208 a is less than N_(max), then all of the neighbor nodes 208 may be displayed with the node of interest 208 a. If, however, the number of neighbor nodes 208 corresponding to the node of interest 208 a is greater than N_(max), then only N_(max) neighbor nodes 208 may be displayed at a time. In the depicted example, N_(max)=10. Therefore, although the node of interest 208 a includes a total of 22 neighbor nodes 208, only 10 of those neighbor nodes 208 are displayed at a time.

The visual representation 118 includes a user interface element 222 that provides information about the subset of neighbor nodes 208 that are currently being displayed. In the depicted example, the user interface element 222 indicates which neighbor nodes 208 are currently being displayed (neighbor nodes 1-10), as well as the total number of neighbor nodes 208 that correspond to the node of interest 208 a (22).

The user interface element 222 also facilitates navigation to the additional neighbor nodes 208 that correspond to the current node of interest 208 a but are not currently displayed. In the depicted example, the user interface element 222 includes a left arrow 226 and a right arrow 228. In the user interface screen 224 a that is shown in FIG. 2A, the first set of N_(max) neighbor nodes 208 (neighbor nodes 1-10) are currently being displayed. User activation of the right arrow 228 changes the visual representation 118 so that the next set of N_(max) neighbor nodes 208 (neighbor nodes 11-20) are displayed.

If the first set of N_(max) neighbor nodes 208 are displayed (as in FIG. 2A), user activation of the left arrow 226 may change the visual representation 118 so that the last set of N_(max) neighbor nodes 208 are displayed. Alternatively, if the first set of N_(max) neighbor nodes 208 are displayed, the left arrow 226 may be disabled or not displayed at all.

In some embodiments, the user interface element 222 may include a different type of navigation component, such as a scrollbar. Alternatively, in embodiments where the visual representation 118 is being presented on a touchscreen display, it may not be necessary for the user interface element 222 to include a navigation component. Instead, the user interface element 222 may simply provide information about which neighbor nodes 208 are currently being displayed, and the user may touch the display in a certain way (e.g., by swiping right or left) to change which neighbor nodes 208 are displayed.

Reference is now made to the user interface screen 224 b shown in FIG. 2B, which shows how the visual representation 118 changes in response to user activation of the right arrow 228. The first set of N_(max) neighbor nodes 208 (neighbor nodes 1-10) are no longer displayed, and the next set of N_(max) neighbor nodes 208 (neighbor nodes 11-20) are displayed. The links 210 that connect the neighbor nodes 208 to the node of interest 208 a are also displayed.

At least some of the neighbor nodes 208 corresponding to the current node of interest 208 a may have their own neighbor nodes 208. A neighbor node indicator 230 may be displayed next to each neighbor node 208 that corresponds to the current node of interest 208 a and that includes one or more of its own neighbor nodes 208.

A user may decide that she is interested in learning more about a neighbor node 208 b that corresponds to the current node of interest 208 a. The user may select a neighbor node 208 b of the current node of interest 208 a to become the new node of interest 208 b. For example, if the user selects the neighbor node 208 b named THING, then the THING node 208 b becomes the new node of interest 208 b. The user may select a neighbor node 208 b by clicking on or otherwise activating the neighbor node 208 b in the visual representation 118.

The user interface screens 224 c-e shown in FIGS. 2C-E show an example of a transition from a current node of interest 208 a (COC 1) to a new node of interest 208 b (THING). Reference is initially made to the user interface screen 224 c shown in FIG. 2C. In response to receiving user input selecting a neighbor node 208 b of the current node of interest 208 a as a new node of interest 208 b, the selected neighbor node 208 b may be moved to the central portion of the user interface screen 224 c.

Next, as shown in FIG. 2D, the neighbor nodes 208 corresponding to the previous node of interest 208 a (i.e., neighbor nodes 1-10) may be removed from the visual representation 118. Then, as shown in FIG. 2E, no more than N_(max) of the neighbor nodes 208 corresponding to the new node of interest 208 b may be displayed with the new node of interest 208 b. In some embodiments, the transition shown in FIGS. 2D-E may involve an animated sequence. The neighbor nodes 208 corresponding to the previous node of interest 208 a (i.e., the neighbor nodes 208 that are being removed) may be faded out, and the new neighbor nodes 208 (i.e., the neighbor nodes 208 corresponding to the new node of interest 208 b) may be created around the new node of interest 208 b. Then, the new neighbor nodes 208 may be moved away from the new node of interest 208 b (e.g., similar to a firework) in order to emphasize that the new neighbor nodes 208 are neighbors of the new node of interest 208 b.

If the number of neighbor nodes 208 of the new node of interest 208 b is less than or equal to N_(max), then all of the neighbor nodes 208 corresponding to the new node of interest 208 b may be displayed with the new node of interest 208 b. If, however, the new node of interest 208 b includes more than N_(max) neighbor nodes 208, then a subset of the neighbor nodes 208 corresponding to the new node of interest 208 b may be displayed with the new node of interest 208 b. The user interface element 222 may also be displayed, in order to facilitate navigation to additional neighbor nodes 208 that correspond to the new node of interest 208 b but are not currently displayed. The information provided by the user interface element 222 may be updated to correspond to the new node of interest 208 b. In the depicted example, the total number of neighbor nodes 208 has been updated from 22 (corresponding to the previous node of interest 208 a) to 82 (corresponding to the current node of interest 208 b).

The process shown in FIGS. 2C-E may be repeated each time the user selects a neighbor node 208 to become a new node of interest 208 b. In order to help the user keep track of where she has previously been, the visual representation 118 may continue to display some or all of the previous nodes of interest 208 a when the visual representation 118 is changed to a new node of interest 208 b.

For example, referring to the user interface screen 224 e shown in FIG. 2E, suppose that the user selects the node 208 c named A 305 to become the new node of interest 208 c. The process shown in FIGS. 2C-E may be repeated in order to change the visual representation 118. The resulting changed visual representation 118 is shown in FIG. 2F, in which the A 305 node 208 c is in the central portion of the user interface screen 224 f and a subset of the neighbor nodes 208 corresponding to the A 305 node 208 c are displayed, along with links 210 connecting the neighbor nodes 208 to the A 305 node 208 c. In addition, the previous nodes of interest 208 a-b (namely, the THING node 208 b and the COC 1 node 208 a) are also displayed. Continuing to display the previous nodes of interest 208 a-b in this manner may help the user to be able to more easily traverse the visual representation 118 of the query results 116.

FIG. 3 is a flow diagram that illustrates an example of a method 300 for providing a visual representation 118 of a graph in accordance with the present disclosure. As indicated above, for purposes of example, the visual representation 118 will be discussed in the context of query results 116 for a graph database 106. However, the visualization techniques disclosed herein may be applied in a variety of other contexts, such as visually representing a graph that is loaded from a file.

A query 104 may be received 302 from a query-generating entity 102. The query 104 may be executed 304 against a graph database 106 to obtain query results 116. A visual representation 118 of the query results 116 may be generated 306 and displayed 308 via a user interface 120. The visual representation 118 of the query results 116 may be changed 310 in response to user input.

FIG. 4 is a flow diagram that illustrates an example of a method 400 for displaying 308 a visual representation 118 of query results 116 and changing 310 the visual representation 118 in response to user input. In other words, the method 400 shown in FIG. 4 is an example of the last two operations 308, 310 in the method 300 of FIG. 3.

The query results 116 include a plurality of nodes 208. User input may be received 402 to select one of the nodes 208 as a node of interest 208 a. The node of interest 208 a may be displayed 404 in a central portion of a user interface screen 224 a in which the visual representation 118 is being presented.

If the number of neighbor nodes 208 corresponding to the node of interest 208 a is less than a defined maximum (N_(max)), then all of the neighbor nodes 208 may be displayed with the node of interest 208 a. If, however, the number of neighbor nodes 208 corresponding to the node of interest 208 a is greater than N_(max), then only a subset of the neighbor nodes 208 may be displayed 406 with the node of interest 208 a. A neighbor node indicator 230 may be displayed 408 next to each neighbor node 208 that corresponds to the current node of interest 208 a and that includes one or more of its own neighbor nodes 208. Links 210 connecting the neighbor nodes 208 to the node of interest 208 a may also be displayed 410.

A user interface element 222 may also be displayed 412. The user interface element 222 may provide information about the subset of neighbor nodes 208 that are currently being displayed (e.g., which neighbor nodes 208 are currently being displayed, the total number of neighbor nodes 208 that correspond to the current node of interest 208 a). The user interface element 222 may also facilitate navigation to the additional neighbor nodes 208 that correspond to the current node of interest 208 a but are not currently displayed. For example, the user interface element 222 may include one or more navigation components (e.g., a left arrow 226 and a right arrow 228, a scrollbar). In response to detecting 414 user activation of the navigation component(s), the subset of neighbor nodes 208 that are being displayed may be changed 416.

User input may be received 418 selecting a neighbor node 208 b of the current node of interest 208 a to become the new node of interest 208 b. In response, the selected neighbor node 208 b may be moved 420 to the central portion of the user interface screen 224 c. The neighbor nodes 208 corresponding to the previous node of interest 208 a may be removed 422 from the visual representation 118 (so that those neighbor nodes 208 are no longer displayed). A subset of the neighbor nodes 208 corresponding to the new node of interest 208 b may be displayed 424 with the new node of interest 208 b. The information provided by the user interface element 222 may be updated 426 to correspond to the new node of interest 208 b.

As the user traverses the visual representation 118, the user may select many different nodes of interest 208 a-c. The visual representation 118 may continue 428 to display some or all of the previous nodes of interest 208 a-b whenever the visual representation 118 is changed to a new node of interest 208 c.

FIG. 5 is a block diagram that illustrates another example of a system 500 in which aspects of the present disclosure may be utilized. The system 500 includes a user device 532, such as a personal computer, laptop computer, mobile device, or the like. The user device 532 may be in electronic communication with a query processing system 514 via one or more networks 536. In some embodiments, the network(s) 536 may include the Internet, and the query processing system 514 may be implemented as a cloud computing system.

The user device 532 may include a client application 502 that communicates with one or more application programming interfaces (APIs) 538 of the query processing system 514 in order to make queries 504 with respect to a graph database 506. As discussed above, the graph database 506 may include nodes 508 and links 510. The nodes 508 may include properties 512 a, and the links 510 may include properties 512 b. In some embodiments, the client application 502 may be a web browser that accesses the query processing system 514 via the Internet. Alternatively, the client application 502 may be another type of software application other than a web browser.

The query processing system 514 may execute one or more queries 504 against the graph database 506 to obtain query results 516, which may be returned to the user device 532. The client application 502 may include visualization components 540 that provide a visual representation 518 of the query results 516. The visual representation 518 may include some or all of the aspects of the visual representation 118 described above and shown in FIGS. 2A-F. The visual representation 518 may be displayed to the user via a display device 542 of the user device 532.

In the above discussion, reference was made to a “central portion” of a particular region, such as a user interface screen 224 a. As used herein, the central portion of a region refers to a part of the region that is situated at or near the actual center of the region. For example, a node 208 a may be deemed to be within the central portion of a user interface screen 224 a if a rectangle can be drawn that satisfies the following two conditions. First, the rectangle includes both the node 208 a and the actual center of the user interface screen 224 a. Second, the area of the rectangle is no greater than x percent of the total area of the user interface screen 224 a. In some embodiments, the value of x is 2. In other embodiments, the value of x is 5. In still further embodiments, the value of x is 10.
